How Far Back Should a Systematic Review Go? Guidelines by Research Field
Learn the optimal time frame for systematic reviews across various research fields to ensure comprehensive and relevant results.
0 views
The time frame for a systematic review should be determined based on the research question and the field of study. Typically, a comprehensive review might go back 10 to 15 years to capture relevant studies. However, in rapidly evolving fields like technology or medicine, focusing on the most current 5 to 10 years could be more pertinent. The key is to ensure that the chosen time frame allows for an exhaustive and relevant collection of studies to accurately answer the research question.
FAQs & Answers
- What factors determine the time frame of a systematic review? The time frame depends on the research question and the evolution of the field. A broader time frame may be needed for slower-changing fields, while rapidly evolving areas might require a more recent focus.
- Is it necessary to include studies older than 15 years in a systematic review? Generally, going back 10 to 15 years is sufficient, but older studies may be included if they are seminal or highly relevant to the research question.
- How do systematic review time frames differ across disciplines? In fast-paced fields like technology or medicine, reviews often focus on the past 5 to 10 years, whereas in other areas, a longer historical range may provide more comprehensive insights.
